Time measured in advertising
I am going to see a doctor. I lost some time tonight: stood up as soon as the commercials started, walked towards the door to let the cat in, had to sit down on the floor and have a kind of a blank space there, before I managed to get up, open the door, and get back on the couch... just in time for the movie to start. I told this to the head of the department. His immediate reaction was: "On that channel, that's at least six minutes." I am not sure what worries me more, that I had spent six minutes on the floor, or that somebody actually knows those things at the top of their heads.
